How to Make a Louisiana Roux

Classic Louisiana Roux Recipe |

Without a roux, you can’t make a gumbo. Period. End of story. And it’s not an *authentic* gumbo unless it starts with a classic Louisiana roux. That’s what I’ve been told, anyway.

Butter is used in the more classical French style, but most Cajuns tend to use oil. The secret to a perfect roux is to keep it at medium-high heat, add the flour a bit at a time, and keep stirring it until your arms fall off. I threw out at least a 1/2 dozen of my first-tries, so don’t feel bad if you burn it the 1st (or 5th) time. The ingredient are inexpensive, so just chuck it and start over if you screw it up. And whatever you do, don’t ‘settle‘ and use a slightly over-cooked roux…it’ll takes bitter and ruin your gumbo.
